SPECIFICATION forming part of Letters Iatent No. 636,134, dated October 31, 1899.

I Application filed October 8, 1898. Serial No. 693,036. .(ll'o moclel.)

.10, phones in which a record is kept of each use made of the instrument; and the object of my invention is to provide a device of this class in which a coin or atoken may be employed for operating the register and in providing a I device whereby the coin is retained and the token delivered to the user.

To this end my invention consists in the tie vice as a whole, in the combination of parts,

and in the details and their combination, as.

' so hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a front view of a set of telephone instruments embodying my invention. Fig. 2 is a front :5 view of the toll-box on enlarged scale. .Fig.

3 is a detail front-view of the toll-box, on enlarged scale, with the-cover removed. Fig. it is a detail side view, on enlarged scale, in vertical section, through the toll-box. Fig; 5 is a detail front view, on enlarged scale,of the coin chute, showing the method of operating the register, the cover-plate being removed Fig. 6 is a detail end view, on enlarged scale and in section, through the coin-chute. Fig. 7 is a 3 5 detail top view, on enlarged scale, of the coin chute and attached parts. Fig. 8 is a detail front view, on enlarged scale, of the coin-chute with the front plate removed and showing the parts in position for operating the register;

Fig. 9 is an enlarged detail top view of the,

spring-fork and hammer-lever engaged.

In the accompanying drawings the letter a denotes the backboard, -b"the battery-hex, o the transmitter, dthe receiver, a themagnetobells, and f the toll-box, of a set of telephone instruments of ordinary construction. The toll-box f contains the mechanism for denot ing the uses made of the instrument and also for receiving the coins inserted therein for such use.

In the form shown the toll-box f consists of a base f adapted to be secured to the backboard a in close contact with the support for the tra'nsmitter'c, in the present instance the coil-box e, or in any other manner socons'tructed as to have a metallic connection therewith. The toll-box also consists of a top f and a cover composed of sections f f and a pocket f", the latter being adapted to receive the coins deposited for the useof the instrument and also having 2. lug f for securing the pocket to the remainder of the tollbox. These sections f and f are secured to the base in any suitable manner herein shown, as by means of screws. The pocket f has a lug f located in the socket f on the base.

A bracket f extends from the base f and has secured thereto a coin-chute 9, that leads to a coin-opening f and a token-opcningf in the pocket. A plunger-chamber g is 10- 7o cated in the c0in-chute and extends laterally thereof. A sectional plunger, consisting of a leader h and a follower 1 is located in this chamber, each of said parts having a reciprocating movement therein, The leader h has a handle it and a recessed and h the former extending through a wall of the plunger-chamber and also through the wall of the toll-box f and the latter shaped to lit a token it or coin is, the latter being shown in dotted 8o outline.

' The end of the follower '1'- is inclined, as at '5, to receive the thrust of a coin or token and to force such toward the bottom of the plungerhamber. This follower also bears :1 connesting-lever pin i that extends through a slot and engages the forked end of a connesting-lever Z, pivoted to the coin-chute at y The follower also bears a hammer-lever pin i extending through slots 5 in opposite o walls of the plunger-chamber, one end of the pin losing engaged with a spring m, scoured at one end to the coin-chul-e, and the opposite end-of the pin extending in position to strike a hammer-lever n, pivoted at y 5 The connecting leverl bears a in Z, located in position to thrust against the hammer-lever 'n and force it forward. The hammer-lever bears a hammer 71, adapted to strike and sound a gong o, secured in any suitable posl- Ioo tion in the form shown to the coin-chute g.

The upper end of the hammer-lever engages scenes operation through a reciprocating movement of the plunger being of any well-known and common construction.

The spring-fork maybe of any well-known construction, the branching arms of which are of proper shape and strength to retain the hammer-lever. The extreme ends of the arms may be bent away from each other to aid the passage of the hammer-levers between them.

The coin-chute g has a trap g of a size to admit the entrance of a coin, but permit a token to pass over the trap and follow the chute tothe token-openingf", where it may be received by the person using the instrument, it being intended and the device being constructed for the use of a coin smaller in size than that of the token.

In the operation of the device, the parts being at the position shown in Fig. 5 of the drawings, a coin or token is inserted in the coin-openingf and drops into the plungerchamber g. The plunger is nowoperated by pressure on the handle .h' and the coin or token forced forward against'the follower i, that retreats against the tension of the spring m. The contact of the coin or token with the sloping surface 21 of the follower forces the coin or token downward, which as soon as it reaches the proper position falls through the outlet part of the coin-ch rite,- passing through the trap 9 if it be a coin or passing through the token-openingf if it be a token. As the follower t retreats, as described, the pin 7?, engaging with the connecting-lever l, forces it forward and the lug Z engages the h mmerlever n, held in the grasp of the spri g-fork p, and which is pushed forward, carrying with it the register-plunger p and turning the register forward one step. As the coin or token passes downward through the outlet part of the coin-chute the follower 'i returns through the impulse of the springm, causing the hammer-lever .pin if to strike the hammer-lever and return the plunger to its former position, the blow also forcing the hammer-lever from the grasp of the spring-forks p, causing it to strike the gong 0, from which it recoils and again enters the graspof the spring-forks for a repetition of the operation.

The term traveler is employed in the claims herein to denote coins or tokens of different eonstruction--as difference in diameter, thickness, or othcrwise-and it will be noted that in the device herein described and shown all coins or tokens of one set, all of which said set are of like construction, will be ejected from the machine, while all coinsor tokens of another set, all of which set are of likeconstruction, will be retained in the machine.

7. In a telephone, in combination, a plunger having sections adapted to be connected by a traveler, an indicator, a lever bearing a. sounding device and adapted to operate the indicator, and connections between a section of the plunger and the lever for operating the latter.

8. In a telephone apparatus, in combination, a plunger having sections adapted to be connected by a traveler, an indicator, a hammer-lever adapted to operate the indicator and bearing a sounding device, and. a connectin g-leve r con-neetin g a section of the plunger and the hammer-lever.

9. In a coin-controlledtelephone, in combination, a plunger, means for operating the plunger through the medium of a traveler,
